APPLICATION
Uniform application of VELPAR®
USE PRECAUTIONS - ALFALFA
•Best results are obtained when
•On soils high in organic matter (greater than 5%), the effectiveness of VELPAR® L can be significantly reduced and weed control may be unsatisfactory.
•Crop injury, including mortality, may result in fields with restricted root growth due to nonuniform soil profiles such as gravel bases and clay lenses.
•Crop injury may result if hot weather,
•Do not apply to
•Since the effect of VELPAR® L on alfalfa varies with soil conditions, uniformity of application, and environmental conditions, growers should limit their first use to small areas.
•If abnormally dry conditions exist following application, restrict the first irrigation to no more than 1/2 acre inch of water.
•Temporary yellowing of alfalfa may occur following VELPAR® L applications.
•Treat only stands of alfalfa established for one year or for one growing season (except in California), provided:
below the crown) throughout the field and the crop is healthy, vigorous, and not under stress from weather conditions, low fertility, insects or disease damage.
•In California, fall planted alfalfa may be treated in the following winter months with VELPAR® L at 1 to 2 pints per acre (use higher rate for fine textured soils) provided:
-alfalfa root growth exceeds 6 inches in length
-vegetative top growth of alfalfa has lateral development of secondary growth
-alfalfa is healthy and vigorous, not growing under stress from insect, disease, winter injury or other types of stress.
Injury may result to alfalfa plants that fail to meet these growth criterion listed above.
•Do not use VELPAR® L on seedling alfalfa,
•Do not add a surfactant to VELPAR® L when treating non- dormant alfalfa.
•Do not use VELPAR® L on gravelly or rocky soils, exposed subsoils, hardpan, sand, poorly drained soil, or alkali soils.
SEED ALFALFA (CALIFORNIA ONLY) ADDITIONAL USE PRECAUTIONS
•Do not use VELPAR® L on fields with sandy loam or loamy sand soils having less than 1% organic matter.
•Do not exceed 2 pints per acre on fields with sandy loam or loamy sand soils having
•Do not exceed 2 pints per acre on seed alfalfa that has been established for only one growing season.
BLUEBERRY
HIGH BUSH BLUEBERRIES
VELPAR® L is recommended for control of certain herbaceous and woody weeds in established high bush blueberry fields.
APPLICATION INFORMATION
VELPAR® L may be applied to high bush blueberries that have been established for 3 or more years. Apply VELPAR® L in the spring before blueberry leaf emergence. Direct the spray solution towards the soil and weeds.
Using calibrated ground spray equipment, make the application in sufficient water to provide thorough and uniform coverage to the treated area (usually 20 gallons per acre). Shut off spray booms when starting, turning, slowing or stopping, or injury to the crop may result.
